The effect of testicular binding of human chorionic gonadotropin upon the biological activities of the hormone was examined by comparison of the binding and activation properties of (125)I-labeled gonadotropin before and after binding to rat testis in vitro. Biologically active (125)I-gonadotropin taken up by rat testis was dissocated from testis binding-sites at low pH and evaluated for its ab...

In this study we investigate the expression pattern of mucin genes in the human testis and evaluate the relationship between the expression of mucin genes and impaired spermatogenesis in the human testis. Thirty human testis tissues were collected from patients undergoing diagnostic testicular biopsy to investigate the cause of infertility. One part of the tissue underwent histological observat...

This is a report of bilateral testicular torsion. The objective of the report is to highlight the serious implications of misdiagnosis of testicular torsion. Other than loss of the testis due to necrosis in unilateral torsion, immunological damage of the opposite testis occurs. Early, accurate diagnosis, and institution of the appropriate treatment are desirable to prevent total loss of reprodu...

Abstract Background Energy drinks prevent fatigue and increase physical cognitive performance; however, they also inflict toxic effects on the body. Blueberry (BB) possesses antioxidant anti-inflammatory properties. The present study aimed to assess possible therapeutic of BB testicular damage in adult male Wistar albino rats induced by administering energy drink Code Red. Results Thirty were u...

OBJECTIVE Investigation of the effects of experimental cryptorchidism formed in prepubertal rats during the postpubertal and adult periods. MATERIAL AND METHODS The abdominal cavities of 20 rats in the control group were just opened and closed without any further surgical procedure. The testicles of 20 rats in the experimental group were fixed to the anterolateral wall of the abdominal cavity...

MicroRNAs (miRNAs) are endogenous non-coding small RNAs that can regulate the expression of complementary mRNA targets. Identifying tissue-specific miRNAs is the first step toward understanding the biological functions of miRNAs, which include the regulation of tissue differentiation and the maintenance of tissue identity. In this study, we performed small RNA library sequencing in adult mouse ...

Background: Recent advances showed that oxygen radicals and hydrogen peroxides are linked with the development of several pathological processes associated with chemotherapy, including adverse effects of anti-tumor drugs. Methotrexate (MTX) is an antifolate that is widely used in the treatment of rheumatic disorders and malignant tumors. The efficacy of methotrexate is often limited by severe s...

INTRODUCTION Cisplatin (CP) is a major antineoplastic drug for treatment of solid tumors. CP-induced nephrotoxicity may be gender-related. This is while gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter in the central nervous system that has renoprotective impacts on acute renal injury. OBJECTIVES This study was designed to investigate the protective role of GABA against CP-ind...

The use of testis tissue xenografting as a valuable tool to rescue endangered and genetically valuable individuals that die young or otherwise fail to produce sperm has been the subject of much interest. Although the technique has been successfully applied to a wide variety of species, little is known about what determines the outcome. Furthermore, to improve the applicability of xenografting, ...

Galectin-3, a member of the beta-galactoside-binding protein family, has been implicated in mammalian sperm maturation. We examined galectin-3 expression in the testis and epididymis of sexually mature and immature bulls. Western blot analysis showed varying levels of galectin-3 in the bull testis and epididymis, and galectin-3 immunoreactivity was higher in the mature testis and epididymis tha...
